What Does C0367 Mean?
This code indicates the control module has detected an abnormally high voltage in the front axle actuator control circuit, typically in vehicles equipped with all-wheel drive, four-wheel drive, or electronically controlled front differential systems. The module expected a normal operating voltage range but measured a voltage higher than the specified threshold, suggesting a short to power, open circuit, or actuator malfunction. This affects the vehicle's ability to properly engage or control the front axle drive system.
Common Causes
35%
Wiring harness short to power or damaged insulation causing intermittent short to battery voltage in the front axle actuator circuit
30%
Failed front axle disconnect actuator or front differential actuator with internal short circuit
20%
Corroded or damaged connector pins at the actuator or control module causing increased resistance or intermittent high voltage reading
10%
Failed transfer case control module or 4WD control module with internal fault causing improper voltage output
5%
Open circuit in ground path causing voltage feedback through control circuit
Diagnostic Steps
1
Step 1: Perform visual inspection of the front axle actuator wiring harness for obvious damage, chafing against components, heat damage, or pinched wires. Check all connectors for corrosion, bent pins, or moisture intrusion at both the actuator and control module ends.
2
Step 2: With ignition off, disconnect the front axle actuator connector and measure voltage on the control circuit wire at the harness side using a digital multimeter. Reading should be 0 volts; any battery voltage present indicates a short to power in the wiring harness.
3
Step 3: Measure resistance of the front axle actuator between control circuit terminal and ground with actuator disconnected. Compare to manufacturer specifications (typically 2-10 ohms for most actuators). Infinite resistance or very high readings suggest internal actuator failure or open circuit.
4
Step 4: Check circuit continuity and resistance between actuator connector and control module connector on the control wire. Should show less than 1 ohm resistance and no shorts to power or other circuits. Also verify ground circuit integrity with resistance less than 1 ohm to chassis ground.
5
Step 5: If all wiring tests pass, monitor live data voltage values on the control circuit while commanding actuator operation through scan tool bi-directional controls. Voltage should modulate properly; sustained high voltage during commanded operation indicates control module fault.
6
Step 6: After repairs, clear codes, perform actuator relearn procedure if required by manufacturer, and road test in conditions that engage front axle to verify proper operation and confirm no code return.

The most common cause of C0367 (Front Axle Control Circuit High) is: Wiring harness short to power or damaged insulation causing intermittent short to battery voltage in the front axle actuator circuit
Typical repair costs for C0367 range from $150 to $1,200, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Vehicle is safe to drive in most conditions but may be stuck in 2WD or experience improper 4WD engagement, which could affect traction in adverse conditions or off-road situations. Repair within a few days, especially if you rely on 4WD functionality for your driving needs.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to C0367 to identify the root cause.
